Well, in principle this filler arc has two problems: The story apparently conflicts with the manga, which pisses off those who read the manga and worries others (as even those who don't read the manga know that's where the awesome original story comes from (and the Kenshin precedent is not something anybody wants to see repeated here)), and secondly the action in these fillers is clearly subpar.Originally Posted by Mae
So, basically the story itself hasn't been such a gross thing, if you ignore the fact it messes with the manga to some extent. The main gripe is the poorly depicted action, and there's simply no excuse for that.
